## Description

On March 16, 2018, the NRC issued a Notice of Violation to Prein & Newhof Inc., for a Severity Level III violation. The violation involved a failure to use two independent physical controls that form tangible barriers to secure a portable gauge from unauthorized removal as required by 10 CFR 30.34(i). Specifically, on multiple occasions between November 9, 2017, and November 17, 2017, the licensee left portable gauges in two different vehicles, each with only one physical control to prevent unauthorized removal when the gauges were not under the control and constant surveillance of the licensee.
